Evaluating the meeting solutions used for virtual classes in higher education during the COVID-19 pandemic
(Institute for Systems and Technologies of Information, Control and Communication, 2021) Granda Juca, María Fernanda; Parra González, Luis Otto
When the Ecuadorian government put the country into quarantine as a preventive measure against the Covid-19 pandemic the country’s schools and colleges had been working normally up to March 2020. On March 13th, the University of Cuenca decided to suspend face-to-face classes and changed the system to virtual online teaching. Although the teachers and students changed the teaching-learning method from face-to-face to virtual, they were not prepared to continue their education in this new educational system, in which each student’s family had different mandatory elements (e.g., an Internet connection, computer, meeting solution). However, they continued the classes through meeting solutions to continue the school year through virtual classes but without any criteria to select the most suitable meeting tool. This paper evaluates two of the most commonly used meeting solutions for virtual university classes: Webex and Zoom. We used User Experience Questionnaire and Microsoft Reaction Cards to evaluate these solutions. The results showed that Zoom was significantly more attractive than Webex, although there was no significant difference between them in the classic aspects of usability or user experience.
Testing-based conceptual schema validation in a model- Driven environment
(CEUR-WS, 2013-06-21) Granda Juca, María Fernanda
In Model-Driven Development, the main artefacts are conceptual schemas, and efforts are focused on their creation, testing and evolution at different levels of abstraction through transformations. If a conceptual schema has defects, these are passed on to the following stages, including coding. Therefore, techniques for improving the quality of conceptual schemas must be implemented to assure the correct generation of final software products. One of the challenges in Model-Driven Development is being able to identify defects early on, at the level of conceptual schemas, as this would help reduce development costs and improve software quality. In this research proposal we suggest an approach for testing-based conceptual schema validation in order to improve quality.

Evaluating Extended Reality Application for a Virtual Museum. Case Study: Remigio Crespo Museum.
(Institute of Electrical and Electronics Engineers Inc., 2023) Parra Gonzalez, Luis Otto; Barreto Paredes, Christian Fabian; Agudo Guiracocha, Dayana Isabel; Granda Juca, María Fernanda
The COVID-19 pandemic was the main reason why many organisations decided to include information and communication technologies in their processes to allow them to continue with their activities, be it providing services to users (food, medicine, etc.), training/education or disseminating culture. In the field of culture, some museums incorporated technology into their operating environment, moving from face-to-face visits to virtual visits. However, in many museums, the lack of apps designed to solve the problem of virtual visits caused some to stop receiving visitors during the pandemic. In this context, this paper describes the development of an application with a user-centred design that incorporates extended reality to allow virtual visits to the Remigio Crespo Museum in the city of Cuenca (Ecuador). The evaluation carried out to verify the application's usability and learnability is also included. The results obtained indicate that users/visitors found the application usable and easy to learn
Mutation operators for UML class diagrams
(Springer, Cham, 2016) Granda Juca, María Fernanda; Condori Fernandez, Nelly; Vos, Tanja Ernestina; Pastor López, Oscar; Granda Juca, María Fernanda
Mutation Testing is a well-established technique for assessing the quality of test cases by checking how well they detect faults injected into a software artefact (mutant). Using this technique, the most critical activity is the adequate design of mutation operators so that they reflect typical defects of the artefact under test. This paper presents the design of a set of mutation operators for Conceptual Schemas (CS) based on UML Class Diagrams (CD). In this paper, the operators are defined in accordance with an existing defects classification for UML CS and relevant elements identified from the UML-CD meta-model. The operators are subsequently used to generate first order mutants for a CS under test. Finally, in order to analyse the usefulness of the mutation operators, we measure some basic characteristics of mutation operators with three different CSs under test.
CoSTest: a tool for validation of requirements at model level
(Institute of Electrical and Electronics Engineers, 2017) Granda Juca, María Fernanda; Condori Fernandez, Nelly; Pastor López, Oscar; Vos, Tanja Ernestina; Granda Juca, María Fernanda
We present CoSTest, a tool that supports the validation of Conceptual Schemas by using testing. The tool implements techniques for transforming instantiations from a Requirements Model into test case implementations by supporting a Model-driven architecture.

How do negative emotions influence on the conceptual models verification?: a live study proposal
(Association for Computing Machinery, Inc, 2020) Mayhua Quispe, Angela; Suni Lopez, Franci; Granda Juca, María Fernanda; Condori Fernández, Nelly
The present live study is proposed with the objective of investigating the influence of negative emotions (i.e., stress) in the efficiency for verifying conceptual models. To conduct this study, we use a Model-driven Testing tool, named CoSTest, and our own version of stress detector within a competition setting. The experiment design, overview of the empirical procedure, instrumentation and potential threats are presented in the proposal.
UI-Test: a model-based framework for visual UI testing– qualitative and quantitative evaluation
(Springer, 2022) Parra González, Luis Otto; Alba Sarango, Bryan Andrés; Granda Juca, María Fernanda
During the testing stage in the software development life cycle, developers can take advantage of combining the requirements specification with the testing specification. This will allow the specification of the tests to require less manual effort, since, they can be defined or generated automatically from the require-ments specification. The requirements specification will thus be based on a more structured language, gaining in quality and reducing ambiguity, incon-sistency, and inaccuracy. In this research work, the UI-Test model-based meth-odological framework and its tool support are proposed. Both of these can gen-erate evidence based on the specification of agile user stories that are used in the validation of the functional requirements that must be included in the final version of the user interfaces of the developed software. Our proposal makes use of two model transformations to obtain the test scripts from user stories that will be applied in the process using SikuliX for automated visual UI testing. The results of the empirical evaluation of the effectiveness and user experience of the framework and its tool support suggest that the UI-Test tool can benefit testers by confirming that the actions proposed in the user stories can be run on the UIs.
A Methodology to Develop Extended Reality Applications for Exhibition Spaces in Museums
(Institute of Electrical and Electronics Engineers, 2022) Granda Juca, María Fernanda; Barreto Paredes, Christian Fabián; Agudo Guiracocha, Dayana Isabel; Parra González, Luis Otto; Parra González, Luis Otto
Web 2.0 brought the development of social networks and new elements of interaction that were incorporated into Web sites and devices that supported them. In the field of museums, the emergence of Web 2.0 and Museum 2.0 has made it possible to improve access to information regarding art collections. Due to the COVID-19 pandemic, museums have opted for the introduction of technology permitting virtual access to their collections. However, many applications were developed using traditional development process without considering a methodology dedicated to extended reality applications. This paper describes a methodology for the implementation of extended reality applications to exhibition spaces in museums. Using a quasi-experiment, we evaluate the data collection stage of the proposed methodology to develop an extended reality application to visit exhibition spaces in a museum. Results show that the proposed methodology helps to the software engineers/designers in the development process of extended reality applications.
